复制代码 代码如下:

$link=mysql_connect("","","")
or die("无法连接到mysql数据库".mysql_error());
mysql_select_db("duyounet",$link);
mysql_query("SET NAMES 'gb2312'",$link);
$day30=time()-60*60*24*30;
$result=mysql_query("select articleid,articlename, (allvote*20+goodnum+allvisit) as dxy_px from jieqi_article_article where postdate>$day30 order by dxy_px desc limit 0,14") or die("查询".$database."数据库出错".mysql_error());
$row=mysql_fetch_row($result);
echo "document.writeln("")".";rn";
while ($row){
echo "document.writeln("
  • ".$row[1]."(".$row[2].")
  • ");rn";
    $row=mysql_fetch_row($result);

    }
    mysql_free_result($result);
    mysql_close();
    echo "document.writeln("");rn"
    ?>

    如果在PHP中处理,用strtotime
    [php]
    $a="2004/11/01";
    $b=strtotime("+6 months",strtotime($a));
    echo date('Y/m/d',$b);
    [/php]
    如果在mysql中处理,用DATE_ADD或ADDDATE函数,也可以直接使用INTERVAL关键字
    如:
    1、SELECT "2004-11-01" + INTERVAL 6 MONTH;//其中的2004-10-01可以直接使用日期字段
    2、SELECT DATE_ADD("2004-11-01", INTERVAL 6 MONTH);
